"While the skies were clear the seeing conditions were quite poor due to high humidity," Hancockwrote SPACE.com in an email.

Astrophographer Terry Hancock sent SPACE.com this image of the Bubble Nebula, or NGC 7635. He captured the photo from Down Under Observatory in Fremont, Mich. after 11 hours of exposure time over three nights in August.

Approximately 6 light-years wide, NGC 7635 is located roughly 7,100 light-years from Earth in the constellation Cassiopeia. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers). Intense radiation and stellar winds from a nearby star created this delicate-looking bubble, which shines pink because of surrounding red, hot gas.
